ATTACHMENT FOR HAY-LOADERS.

To all whom it may concern:

Be it known that we, PAUL RUSSELL LovnLL and ERNEST HENRY MICHAEL, citi-Zens of the United States, residing at Logan, in the county'of Harrisonand State of Iowa, have invented certain new and useful Improvements inAttachments for Hay-Loaders; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention is an attachment for the usual form of cylinder hayloader.

The objects of the invention are to provide hay loaders with improvedmeans whereby the hay may be delivered at the center of the hay rack, isprevented from being drawn back by slack chains, is prevented fromaccumulating under the conveyor, is prevented from being blown back orside- ,wise when discharged on the rack, and may be'loaded very high onthe rack.

With these and. other objects in view the invention consists of certainnovel features of construction, and the combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings: Figure 1 is a side view of a cylinder hayloader illus- "trating the application of the invention and showing thelatter in an operative position; Fig. 2 is an enlarged verticallongitudinal sectional view of a portion of a loader showing theattachment'in a raised or inoperative position; Fig. 8 is a rear View ofthe same with the attachment in a lowered or inoperative position; Fig.4 is a perspective view of a portion of the conveyer frame of the loadershowing the conveyer attachment engaged therewith and in an operativeposl- -tion.

' Our attachment comprises an adjustabl extension adapted to be appliedto the uppe end of the conveyer frame of the ordinary or any form ofcylinder hay loader and consists of a series of bars 1 the inner ends ofwhich are hingedly connected to the upper shaft 2 journaled in the upperends of standards 80 of the conveyer mechanism of the loader. The bars 1are preferably hingedly connected to the shaft 2 by U-shaped strap irons2 and supported in a similar manner on the outer ends of the bars is aconveyor shaft 3. On the shaft 3 are revolubly mounted flanged pulleywheels t around which are adapted topass the chains 4 of the conveyerSpecification of Letters Patent. Application filed August 31, ion.

mechanism of the loader, said chains being extended or increased inlength to reach the pulley wheels 4. The upper stretches of the chains 4pass over the usual flanged pulley wheels 5 on the shaft 2 of theconveyer mechanism of the loader and the lower stretches of the twoouter chains 4 are supported by idle sprocket wheels 6 which arerevolubly mounted in suitable supporting brackets 7 secured to andprojecting at a suitable angle from inclined attachment supporting bars8 which are secured at their lower ends to the main frame of the loaderand are secured intermediate their ends to the sides of the conveyerframe of the loader by suitable brackets or hangers 9 as shown. Theupper ends of the bars 8 project a suitable distance above the upper endof the conveyer frame of the loader and are connected together y acrossbar 10. The bars 8 are further braced and supported by inclinedbrace wires 11 which are secured at their upper ends to the upper endsof the bars 8 and at their lower ends to the frame of the loader asshown.

The conveyer chains at are connected together by the usual hay elevatingslats 12 which are secured to the chains at suitable intervals and inthe usual manner and serve to support the lower stretch of the middlechain 4' whereby an idler sprocket wheel 6 under the rhain is dispensedwith. The bars 1 of the extension are preferably secured together andbraced by a diagonally arranged brace bar 15 disp sed beneath the bars 1and secure at one end to the inner end of one of said bars 1 and at itsopposite end to the outer end of the opposite side bar 1 as shown. Theconveyor extension when thus constructed andarranged is adapted to beraised and Patented Feb. 13, 1912,

lowered and supported at the desired angle with respect to the upper endof the con veyer or elevatlng mechanism of the loader by means ofelevatin cables 14 which are .as shown in Fig. 2.

The lower stretches of the chains 4 after passing over the sprocketWheels 6 are preferahl supported or held up by idle sprocket Wheels It?suitably mounted on a shaft 18 journalcd in hearinghrackets 18 securedto the side hare 8 whereby the slack in the lower stretches of the chainis tekenup and the latter thus prevented from coming into engagementwith the hay when loaded on the Wagon. ldy thus constructing and erranging the attachment it will be seen that the same may be adjusted todeliver the hay at any desired elevation on the hay rack or loader andthat as the size of the load in creases the attachment may he raisedthus permitting a much larger load to be formed.

In. addition touthe hay loading or distributing mechanism just describedWe also provide means for preventing the hay from being blown hack orsidctvise from the deliver-111g attachment, said means comprising aseries otcompressor or protecting slats 19 wl'iich are hingedlyconnected at their innerends to the upper ends of the cone pressor slatsQ0 of the loader and form a continuation ole-extension. of saidcompressor slats. The extension slats l9 correspond in length to thelength. of the conveyor attachment and are connected. together neartheir outer ends by a cross bar 21. The exten" sion compressor slats 19are adapted to be raised and lowered and supported in adjusted positionswith respect to the conveyor attachment by means of an adjusting Wire orcahle92 which is secured to the cross bar 21 and passed over a pulleysecured to the cross her 10 of the supporting frame, By thus adg'ustablysupporting the slats .19 they may he raised and held at the properposition shove the conveyor attaclnnent to prevent the hay from beingblown oil the attachment While being loaded and when the Wind is nothlorviug orthe slats 19 are not required the latter may heswung upwardlyto as out or" the "Way position in line with the main compressor slots20 or the loader. By means of this attachment the delivery ot the hayfrom the loader may be con trolled and the hay discharged at the centeroi the rock and by adjusting the attachment,

accumulation of hay'oeneath the elei 'ating mechanism of loader will heeffectually prevented. The extension slats Will effectually prevent thehay from being hlowuofi" the delivery end of the elevating mechanismwhen discharged onto the reel l From the foregoing description taken inconnection with the accompanying drawings, the construction andoperation of the invention will be readily understood Without requiringa more extended explanation timer aorness form, proportion Variouschanges 5. the

construction may and the minor details of be resorted to Withoutdeparting from. the principle or sacrificing any of the advair tages ofthe invention as claimed.

Having thus described our what We claim is 1. The combination with amain endless elevator belt and an extension thereof at its upper endadjustable to positions in line with or-at an angle to the main hell, ofcompressor slats parallel with the main belt, and an extensioncomprising slats pivoted to the compressor slats at their upper ends andadjustable to maintain a parallel position With relation to the beltextension.

2, The combination with a frame, supporting Wheel and axle for theframe, sprocket Wheels on the aisle, uprights rising from the frame, ashaft journaled in the upper ends of the uprights, an endless clevator'oelt engaging the sprocket Wheels and parallel compressor slats mountedabove the belt, of an attachment pivotally connected on the shaft at thetop of the up rights having sprocket Wheels at its outer ends over whichthe endless belt of the conveyer is carried, a pivoted guard or comprcssor comprising slats in. continuation or" the compressor slats ofthe conveyer, pivoted to the upper ends of said conveyor slats, andmeans whereby the attachment-and pivoted guard may be separately orsimultaneously adjusted at any desired angle to or in alimement with theconveyer uprights.

3. The combination with a frame, two pairs of supportingv uprightsone'of each pair rising from the frame on opposite sides and crossingeach other above the frame, sprocket Wheels at the bottom of the uprights, a shaft at the top of one of the up rights, sprocket Wheels onthe shaft, a frame journaled hingedly on the shaft, sprocket wheelsmounted at the end of the hinged frame, an endless elevator belt passingunder the lower first named sprocket, and the invention,

sprocket at the end of the'hinged frame, and

having its upper stretch passed over the sprockets at the top of oneofthe uprights, two brackets depending from the other upright and ashaft and sprocket journaled in each bracket to support the lowerstretch of the endless belt.

in testimony whereof we have hereunto set our hands'in presence ofsubscribing Witnesses.
